FLOORING.

1 319 286 Specification of Letters Patent.

No Drawing. Application filed November 23, 1918.

To all whom it may concern:

Be it known that we, BENJAMIN F. J OHN- SON and MARTIN BJoRNsrAD, citizens of the United States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Flooring, of which the following is a specification.

This invention relates to improvements in floor covering composition, and the method of making same.

The covering contemplated by this improvement is formed by combining certain specific ingredients which coact when mixed to produce a plastic composition, and when applied to a floor in layers, sets and produces a somewhat resilient or yielding covering having the characteristics of linoleum.

Sawdust, dry mineral (earth) and ground gypsum or plaster of Paris, form the body of the composition, while oil is employed as a binder and as a means for setting the composition.

In carrying the invention into practical use, we properly proportion the ingredients, to make the composition sufiiciently plastic to permit of it being worked when applying to a floor.

The composition consists of a mixture of sawdust, from either hard or soft wood; dry Iowa mineral, (white or gray earth); mineral coloring; plaster of Paris; and Japan oil and Seaware oil combined; these ingredients loeing mixed in the proportions and manner stated in the following formula Sawdust, 1 part coarse and 1 part sifted fine 1 quart. Mineral coloring 1 quart. Dry Iowa mineral (earth) 1 quart.

The Sipes Japan oil used in this comquart.

Serial No. 263,905.

position is composed substantially of the following ingredients:

Black oxid manganese, Raw linseed oil,

Fish oil,

Benzin.

The Seaware oil is composed substantially of the following:

A trace of lead oxid.- A trace of manganese oxid.

made by heating rosin and lime to specific temperature, then adding oil. It is then cooled and thinned with petroleum spirits.

The sawdust, dry mineral coloring and plaster of Paris, are thoroughly mixed in a dry state, and then the oil is gradually added, while the mixture is stirred or agitated to insure of the dry particles being absorbed or thoroughly intermingled with the oil.

The dry mineral and plaster ofParis become intimately worked into the particles of sawdust, and form a body which is somewhat elastic. The oil acts as a binder to hold the dry elements of the mass and forms a somewhat resilient product.

In use, the plastic composition is spread on a floor in a thin layer, the oil dries out and the product sets. Then other layers are applied depending upon the thickness of the covering desired.

It has been found from practical use that a covering produced by the composition described is tough; is waterroof; and is somewhat resilient; and can e hard wear.

What we claim is 1. A floor composition consisting of 1 quart of sawdust; 1 quart of dry mineral (earth); 1 quart of mineral color; g; of a subjected to quart of plaster of Paris; and of a quart of Sipes Japan oil and Seaware oil miXed together.

2. The method of producing a floor covering consisting in mixing together equal parts of dry sawdust, dry mineral (earth), plaster of Paris, subsequently slowly mixing With the dry mixture an oil binder consisting of half part Sipes Japan oil and 10 half part SeaWare oil to form a plastic composition, and then spreading the plastic composition in a thin layer to set.

3. A fioor composition comprising sawdust, dry mineral earth, mineral coloring,

plaster of Paris, and a mixture of Sipes 1 Copies of this patent may be obtained for five cents each, by addressing the Cummissioner of Patents, Washington, D. G.
